PROBLEM TO BE SOLVED: To provide a polymer functional film which has high monovalent ion selective permeability and through which salt hardly leaks, to provide a production method of the polymer functional film, and to provide a laminate and a device each of which includes the polymer functional film.SOLUTION: The polymer functional film is: an anion exchange film containing an acrylic resin and/or a resin having a structural unit shown by the formula CL-1; or such a cation exchange film that a surface layer, which contains a polyamide resin having a cross-linked structure, is formed on the cation exchange film containing the acrylic resin. In the formula CL-1, Land Lare each an alkylene group or an alkenylene group independently, Rand Rare each an alkyl group or an aryl group independently or can be bonded to each other to form a ring, n1 and n2 are each an integer of 1-3 independently, and Xand Xare each an organic or inorganic anion independently.SELECTED DRAWING: None |
